Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
All voltage values are with respect to GND, with GND and OGND
shorted (unless otherwise noted).
Note 3:
When these pin voltages are taken below GND or above V
DD
, they
will be clamped by internal diodes. This product can handle input currents
of greater than 100mA below GND or above V
DD
without latchup.

Note 5:
Integral nonlinearity is defined as the deviation of a code from
a “best fit straight line” to the transfer curve. The deviation is measured
from the center of the quantization band.
Note 6:
Offset error is the offset voltage measured from –1/2LSB when the
output code flickers between 00 0000 0000 0000 and 11 1111 1111 1111
in 2’s complement output mode.
